Over the course of two days in the autumn of 1941, thousands of people were shot in Babyn Yar, on the outskirts of Kyiv. The extent of the punitive action only became known after the liberation of the city from Nazi invaders. But historians continue to study archival documents. Declassified materials that are capable of dispelling the myths of Soviet propaganda about the role of the Ukrainian police, shed light on the nationality of the victims and reveal who actually carried out the shootings.
